摘要

背景点计数串行图像指数(PCSI)是一种用于评估黄褐斑面积和严重程度的评分方法。双重追踪和无法评估分散的色素沉着是其局限性。目的将盒计数序列图像指数(BCSI)与PCSI进行比较和验证,提出对PCSI的改进。方法在BCSI中放置预设网格,采集序列图像。一粒色素沉着计为一盒。主要研究者和共同研究者分别采用BCSI和PCSI方法记录涉及的面积和花费的时间。在0-5的范围内记录色素沉着的强度。黄褐斑评分=面积x色素沉着强度。分析了总分和所用时间的差异。结果:血清素含量显著降低(p

Box counting serial image index (BCSI) versus point counting serial image index (PCSI) in scoring melasma: A comparative, non-interventional validation study.

Background Point counting serial image index (PCSI) is a scoring method used to assess the area and severity of melasma. Double tracing and the inability to assess scattered pigmentation are its limitations. Objectives To propose modifications to PCSI, the Box counting serial image index (BCSI) was compared and validated with PCSI. Methods In BCSI, a preset grid was placed, and serial images were captured. One speck of pigmentation was counted as one box. The area involved and time taken were recorded by the principal investigator and coinvestigator using BCSI and PCSI methods, respectively. The intensity of the pigmentation was recorded on a scale of 0-5. Melasma score = Area x Intensity of pigmentation. The difference in the total scores and time taken were analysed. Results A significant decrease (p<0.0003) in the total scores between baseline and first follow-up and baseline and second follow-up was observed in both methods. Similarly to PCSI, BCSI was found to be sensitive to changes over time with treatment (p<0.0003). These p values were recalculated using Bonferroni corrections. The mean time taken by PCSI was significantly higher than BCSI (p < 0.0003). Limitations Grid placement over bony prominences and interference of facial hair. Conclusion BCSI overcomes the limitations of PCSI by directly capturing images and it is easy and rapid.

期刊介绍: The Indian Association of Dermatologists, Venereologists & Leprologists (IADVL) is the national association of Indian medical specialists who manage patients with skin disorders, sexually transmitted infections (STIs) or leprosy. The current member strength of the association is about 3800. The association works for the betterment of the specialty by holding academic meetings, printing a journal and publishing a textbook. The IADVL has several state branches, each with their own office bearers, which function independently within the constitution of the IADVL. Established in 1940, the Indian Journal of Dermatology, Venereology and Leprology (IJDVL, ISSN 0378-6323) is the official publication of the IADVL (Indian Association of Dermatologists, Venereologists and Leprologists).
